The application of unshaped refractories in glass kilns is gradually increasing, mainly in the following aspects:

I. Regenerator

The unshaped refractory can be used in many parts of regenerator, such as the bottom arch of checker brick, the wall and the arch of regenerator, etc. For example, in Britain, refractory concrete precast blocks are used to build regenerator, which greatly reduces the joints of kiln structure, improves the furnace building speed and shortens the cold repair time.

II. Pool bottom

The bottom of the tank is one of the key parts of the glass kiln, and the application of unshaped refractories in the bottom of the tank is more and more extensive. For example, ERSOL series unshaped refractories from Xipu, France, which are matched with fused bricks and used at the bottom of the pool, have excellent glass corrosion resistance, and have a weak tendency to precipitate bubbles and form stones. ER2SOL series amorphous materials have been used in the bottoms of some glass kilns in Japan.

III. Pond wall

The pool wall is usually made of unshaped refractory with excellent corrosion resistance, such as zircon ramming material or zircon hot patching material. These materials can effectively resist the erosion of molten glass and prolong the life of the kiln.

IV. Other parts

Unshaped refractories can also be used in the flue, small furnace supporting plate, burner and other parts of glass kiln. These parts are usually built with refractory concrete precast blocks, which reduces the joints and improves the integrity and service life.

V. Advantages

Reduce joints: unshaped refractory can reduce the joints of kiln structure and improve integrity and sealing.

Convenient construction: the construction speed is fast, which can significantly shorten the cold repair time.

Strong corrosion resistance: materials such as zircon ramming materials have excellent glass corrosion resistance and are suitable for key parts of glass kilns.

The application of unshaped refractories in glass kiln is the future development trend, and its performance and application scope are still expanding.
